BROOM-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 457,850, dated August18, 1891.

Application filed May 15, 1890. Serial No. 351,965. (No model.)

To all whom it may concern.-

Be it known that I, HENRY K. lRIssEY, a citizen ofthe United States,residing at Hubbard, in the county of Hardin and State of Iowa, haveinvented a new and useful Sewing-Machine, of which the followingisaspecification.

This invention relates to sewing-machines adapted to sew a zigzag line;and the object of the invention is to provide a machine of the charactermentioned which is adapted to form such line of stitches, especiallythrough brooms.

To this end the invention consists of the general arrangement andspecific construction of parts hereinafter more fully set forth, andillustrated in the drawings, in which Figure 1 is a general frontelevation of the machine complete. Fig. 2 is a rear elevation of thesame. Fig. 3 is an elevation in detail of the main operating-shaft andconnections as viewed from the rear side of the machine. Fig. t is aplan view of the sh little-operating mechanism. Fig. 5 is a centraltransverse section of the broom-handle-holding frame. Fig. 0 is aperspective detail of the lower disk, and Fig. '7 of the upper disk, forholding the inner ends of the broom-handles. Fig. 8 is an end View ofthe machine. Fig. 9 is a plan view of the broom-holding devices, showingthe manner in which the brooms are wrapped and the style of stitchesthat are taken therethrough by this machine.

Referring to the said drawings, B is the base of this machine, carriedupon which is a framework F, in which is journaled and supported theseveral shafts and other mechanism forming parts of the whole, and whichframe-work also carries the machine-table T, upon which the sewing isdone.

The driving shaft 1 is journaled transversely through the frame-work F,is cranked, as at 2, has a driving-pulley3 on its front end, and has abevel gear-wheel 4 upon its rear end, all as seen.

The main operating-shaft It) stands in an upright position in theframe-work and is rotated through the instrumentality of a bevel-gear11, meshing with the bevel-geart, just mentioned. This shaft carries agearwheel 12, and has a crank 13, for a purpose to be set forthhereinafter, and the upperend of its body is bent out of a straight linebetween its extremes and provided with a shoulder 14:.

15 is an arm mounted loosely at its rear end upon the oblique portion ofthe main operating-shaft 10 and having a socket in its front end. Inthis socket loosely slides a pin 16, which is pivoted to the needle-bar17, the latter reciprocating Vertically through guides G in thesupporting-head H of the sewingmachine. This head is of L shape, andrises from the bar 23, described below, and at its outer upper end it isprovided with upwardly and downwardly extending arms carrying the guidesG, all as best seen in Fig. 1. A guiding-barf, extending forwardlyfromthe upper part of the frame-work F, engages an eye 72- on the head H andsteadies its movement. The said gear-wheel l2 meshes with a gear-wheel21, mounted upon a vertical axis 20, and to this gear-wheel is connecteda cam 22. A bar 23 slides loosely longitudinally of the frame-work F ona guiding-barf 7;

below the table T, and has a slot 2% engaging the axis 20 of the gear 21and cam 22, and pivoted to this bar 23, in front and in rear of the cam22, are friction wheels or rollers 25. It will thus be seen that whenthegear-wheel 21 rotates the bar 23 will be moved, and as theneedle-guide-supporting head H of the sewing-machine is connected tothis bar it will also move therewith from and toward the v theneedle-bar and its supporting-head are 7 moved out and in theshuttle-plate S, and with it the shuttle, are also moved, so that thelatter will always stand in the proper plane below the needle.

3O isa plate mounted on the threaded stud 31 at the rear side of theframe-work F, and

32 is a thumb-nut on the free end of saidstud, by means of which theplate 30 can be adjusted at any desired angle. 'Pivoted in the upper endof this plateis a crank-arm33, and to the free end of this arm isconnected at pitman 34, by means of which the shuttleis reciprocatedsimultaneously with the movements of the free end of said crank-arm.Said movements are imparted by a connecting-bar 35, connecting the crankof the crank-arm 33 with the crank 13 of the main operatingshaft, andthrough the instrumentality of this connecting-bar reciprocatory motionis thus imparted to the shuttle by the rotary motion of the mainoperatingshaft 10. As the plate IO is adjusted in its angle to theframe-work,

the free end of the crank-arm 33 is raised or lowered, and while thisadjustment will have no effect upon the length of the movementof theshuttle, still it will effect the points from I 5 which said movementscommence and at which they finish.

I have not considered it necessary to de scribe and illustrate in detailthe devices for carrying the threads and feeding them to the 20 needleand to the shuttle, as such devices may be any of those ordinarilyemployed for this purpose.

40 is a rotating shaft mounted in a step 41, and 42 is a wheel carriedby said shaft and 2 5 having notches 43 in the lower edge of itsperiphery. Mounted upon the hub of this wheel is a disk 44, having anumber of cleats or guides secured to its upper face, between which areradial slots 45. The upper end of 0 the shaft 40 is screw'tln'eaded, andmounted loosely on this vertical portion above the disk 44 is a plate46,upon the lower face of which is formed a spiral rib or projection 49.

47 are blocks sliding in the radial slots 45,

which blocks are provided with notches 48 in their upper edges, wherethey project above the guides or cleats, and the spiral rib 49 engagesthese notches. It will thus be seen that when the plate 46 is turnedupon the shaft 40 the several blocks 47 will be caused to move inwardlyor outwardly in the slots 45.

52 is a ring corresponding in size with the periphery of the wheel 42,and to lugs 50 on the interior of this ring are pivotally connected thebifurcated lower ends of links 51. The upper ends of these links are inturn pivotally connected to the outer ends of the bifurcated levers 53,the latter being pivotally supported at their centers upon uprights 54,mounted upon the spokes of the wheel 42. The inner ends of the leversare reduced and enter holes formed ina sleeve 55, which slides looselyupon the shaft 40 and has L-shaped 55 arms 56 at its upper end.

57 is a hand-wheel whose hub engages the threads on the shaft 40, andwhose hub also has an annular groove 58, in which the feet of theL-shaped arms are loosely engaged.

60 It will thus be seen that when thehand-wheel 57 is turned the sleeve55 is raised and lowered, and this motion oppositely lowers and raisesthe ring 52. The ring 52 and the periphery of the wheel 42 carry notchedplates P, whose notches register with each other, as seen in thedrawings and as will be clearly understood.

60 is an arm having a pin 61 in its outer end adapted to engage thenotches 43 in the periphery of the wheel 42. This arm is pivotod betweenits ends to the upper end of a rock-lever 62, which rock-lever is inturn pivoted between its ends to the frame-work F. The lower end of thisrock-lever is pivotally connected by a pitman (53 with the crank 2 ofthe drivingshaft 1, whereby when said shaft is rotated the arm 60 willbe given a longitudinal reciprocation, as will be clearly understood.The inner end of the arm 60 is connected by a connecting-rod 64 with thesaid crank 2 in the driving-shaft 1, whereby when said shaft rotates thesaid inner end of the arm 60 will be given a vertical reciprocation, andthis arm, receiving in this manner a simultaneous longitudinal motionand rocking motion over its central pivot, moves its pin 61 in anapproximately rectangular course. This movement of the pin causes it toengage one of the notches 43 as it moves upwardly, turns the wheel 42the distance between two of the notches as it moves outwardly,disengages the notch as it moves downwardly, and returns to its normalposition as it moves inwardly. In order to cause the pin 61 to remainelevated while the pitman 63 is moving it outwardly and in order to givethe arm 60 its proper motions, the pitman 63 and the connecting-rod 64are slotted, as at 65, where they are mounted on the crank 2, as will beclearly understood.

\Vith the above construction of parts the operation of this machine willbe as follows: lVhen the driving-shaft is rotated, the mainoperating-shaft is also rotated, as above described, and by the rotationof this latter shaft the needle is caused, with the assistance of theshuttle, to make stitches, as will be readily understood. The movementsof the cam 22 are so timed that the head H of the machine,

and with it the needle and shuttle, will be moved outwardly and inwardlyjust at the proper moments relatively to the movements of the needle andshuttle to cause one stitch to be made at the inner and the next at theouter extreme of the movements of the head. The brooms are insertedbetween the plates P, with their handles in the grooves 45 against theblocks 47, after which the plate 46 is turned so as to adjust the broomsto a proper position. The hand-wheel 57 is then turned upwardly on thescrew-shaft 40, whereby the ring 52, carrying the upper plate P, isbrought down upon the heads of the several brooms, firmly clamping themagainst the lower plate P. The rotation of the drivingshaft 1 alsoimparts the above-described movement of the pin 61, which movement turnsthe wheel 42, carrying the brooms, and the parts of the machine are sotimed that this turning of the brooms occurs between each two stitchesand while the head of the machine is moving inwardly or outwardly. Inthe operation of sewing brooms the heads of the latter, after they areput in place between the notched plates P, are first Wrapped with cord,the latter making several complete turns around the broom-head and beingled from one broom to the next without breaking or cutting it. Themachine is then started and operates as above described, the stitchwhich is made at the outmost position of the head H passing through thenotches in the plates P and above the cords which are wrapped around thebroomhandle and the next successive'stitch (when the head II isretracted) standing opposite the points between the notches in the plateP and passing through the broom-head below the cord, whereby the sewingwhich is done through the broom-head is done in zigzag lines and eachstitch passes over the cords which are wrappedaround the broom-head. Thebrooms can be adjusted out or in the wheel by the plate 46, as abovedescribed, and the several adjustments of which the machine is capableare useful for the purposes above described in connection therewith, allas will be clearly understood by a person familiar with this class ofmachines.
